the mounting seat 2 is provided with the mounting groove 21 that holds cylindrical base 13 one by one on it, and the peripheral evenly distributed in cell body 121 bottom of mounting groove 21 has at least three air vent 22 of being connected with outside air supply, and cylindrical base 13 sets up with the mounting groove 21 laminating, still includes sealed lid 23, and the seal cover is established in cylindrical rod body 11 periphery, and seals the open end of mounting groove 21.
In the invention, taking four detection rod bodies 1 as an example, four detection rod bodies are used for detecting four fixing holes on an elevator guide rail, wherein when the installation grooves 21 are processed, the position precision among the installation grooves 21 is required to be ensured to meet the final position precision among the fixing holes, the number of the first channels 112 and the second channels 132 can also be actually selected, but the uniform distribution is required to be ensured, and the specific using steps are as follows:
s1: an external air source is subjected to isobaric ventilation in each mounting groove 21 through the vent holes 22, the cylindrical base 13 keeps stable in position in the mounting grooves 21 under the action of air, and part of the air flows out through the second channel 132, the second countersunk air passing hole 131, the first countersunk air passing hole 111 and the first channel 112 in sequence;
in the above steps, the vent holes 22 are distributed around the cylindrical base 13, and force is equally applied around the cylindrical base 13, so that the cylindrical base 13 is kept at a position relative to the center without the action of external force, and the collision between the elevator guide rail and the tool can be effectively avoided;
s2: the elevator guide rail hole position detection tool and the elevator guide rail move relatively, and each fixing hole is sleeved on the periphery of each cylindrical rod body 11 through the guide of a conical head 12;
in the process, the detection rod body 1 may have slight position change, and the slight change is allowed and flexibly realized because the bottom of the cylindrical base 13 is positioned by annular gas;
s3: when the relative movement is to the set position, the fixed hole side wall seals the outlet end of the first passage 112;
after the step is completed, the outlet end of the first channel 112, which is originally deflated, is blocked, and the blocking effect is different according to the dimensional accuracy of each fixed hole, such as the specific deviation degree of the inner diameter, so that the gas can leak in different degrees, but the detection is performed by applying the deviation in the invention;
s4: detecting the gas pressure at the set positions among the second channel 132, the second countersunk gas passing hole 131, the first countersunk gas passing hole 111 and the first channel 112, and determining the shape and the precision of each fixing hole according to the gas pressure change at each gas pressure detection position;

the position accuracy of a specific fixing hole is consistent with that of other fixing holes, but the diameter may be larger or smaller, as shown by comparison in fig. 7 (for convenience of observation, the deviation is enlarged), at this time, the gap between the fixing hole and the detection rod body 1 is different, so that the pressure drop of the gas corresponding to the fixing hole with the shape meeting the requirement is smaller or larger, when the deviation exceeds the set range, the product can be determined to be a defective product, and certainly, the final deviation value cannot be determined here, and the final product confirmation can be realized through manual re-inspection;
the shape accuracy of individual hole sites is consistent with that of other fixed holes, but when the position is deviated, as shown in fig. 8, the fixed hole at the lower right corner deviates to the left, the gas flowing out from the detection rod body 1 corresponding to the fixed hole (as shown by arrows at four directions corresponding to the detection rod body) will change relative to the fixed hole at the upper right corner in the figure due to the blocking of different degrees, even if the detection rod body 1 at the position is corrected properly under the gas pressure at each direction, the cylindrical base 13 at the bottom of the detection rod body is blocked by the balanced force, so that the change of the pressure is hard to avoid, and the specific change degree is observed by continuously supplying gas, so as to judge the product;
the shapes and positions of the individual holes are deviated, and the above two cases are referred to.
As a preference of the above embodiment, a limiting boss 113 is disposed on the periphery of the cylindrical rod body 11 to limit the elevator guide rail, so as to ensure the position accuracy of the relative movement.
